What is a liver transplant?
A liver transplant is an operation that replaces a failing or severely damaged liver with a healthy liver from a deceased donor or, in selected cases, part of a liver from a living donor. The liver performs hundreds of functions. It processes nutrients, removes toxins, produces bile, supports blood clotting, stores energy, and helps regulate immunity. When liver function declines beyond the ability of medical treatment to control it, transplantation may offer the best chance of longer survival and improved quality of life.
Transplantation is not suitable for every person with liver disease. It is major surgery followed by lifelong specialist care. The decision balances urgency, expected benefit, surgical risk, the likelihood that the patient can follow a complex treatment plan, and the availability of a compatible organ. A multidisciplinary transplant team evaluates each candidate carefully.
Why transplantation may be needed
Chronic liver disease can cause progressive scarring called cirrhosis. Possible causes include chronic hepatitis B or C, alcohol-related liver disease, metabolic dysfunction-associated steatotic liver disease, autoimmune hepatitis, and disorders affecting the bile ducts. Inherited conditions such as Wilson disease, haemochromatosis, or certain childhood metabolic disorders may also lead to transplantation.
Acute liver failure is a rapid loss of liver function in a person who may not have known chronic disease. It can result from certain medicines, toxins, viral infections, autoimmune illness, or other causes. This is a medical emergency, and urgent transplantation may sometimes be required.
Selected patients with liver cancer may also qualify when the cancer meets defined criteria and has not spread beyond acceptable limits. Transplantation can remove both the tumour and the diseased liver in such cases. However, eligibility differs across programmes and must be assessed by specialist teams.
Warning signs of advanced liver disease may include jaundice, abdominal swelling, leg swelling, easy bruising, internal bleeding, severe itching, muscle loss, repeated infections, kidney problems, and confusion caused by hepatic encephalopathy. These features require specialist evaluation. Not everyone with cirrhosis needs an immediate transplant, but timely referral allows the team to assess options before the patient becomes too unwell for surgery.
The transplant assessment
Assessment is extensive because the procedure affects the entire body. It may include blood tests, liver imaging, heart and lung testing, cancer screening, infection screening, dental assessment, nutritional evaluation, and review of kidney function. Doctors examine the cause and severity of liver disease and consider whether another treatment could provide adequate control.
The team also reviews medicines, alcohol or substance use, mental health, social support, and the patient’s ability to attend appointments and take lifelong medication. This process should not be viewed as punishment or judgment. It helps identify risks and arrange support so that the scarce donor organ has the best chance of success.
Some conditions may make transplantation unsafe or unlikely to succeed, such as uncontrolled infection, cancer that has spread, severe irreversible disease in other organs, or inability to tolerate major surgery. Certain barriers may be temporary and reassessed after treatment or rehabilitation.
Waiting for a donor liver
If accepted, a patient may be placed on a waiting list. Allocation systems differ by country, but they generally consider medical urgency, blood group, body size, compatibility, waiting time, and predicted benefit. A place on the list does not guarantee that an organ will become available immediately. Some patients wait months, and their condition may change during that time.
Patients must remain reachable and be prepared to travel to the transplant centre quickly. They continue regular testing so the team can monitor disease progression and ensure they remain fit for surgery. Nutrition, appropriate physical activity, vaccination, infection prevention, and strict avoidance of harmful substances may help maintain readiness.
A potential organ can be declined if tests suggest that it is unsuitable or if the match is not safe. A cancelled operation can be emotionally difficult, but safety comes first. Another offer may occur later.
Deceased and living donation
Most liver transplants use an organ from a deceased donor. A whole liver may be used for one recipient, or it may sometimes be split between two recipients. In living-donor transplantation, a healthy person donates part of the liver. The remaining liver and transplanted portion can grow in volume, although regeneration does not remove the serious risks of donor surgery.
Living donors undergo independent medical and psychological assessment. Their decision must be informed and voluntary, without pressure or financial exploitation. Risks include bleeding, infection, bile leakage, blood clots, and, rarely, life-threatening complications. Donation arrangements must follow legal and ethical national systems.
The operation and early recovery
During surgery, the diseased liver is removed and the donor liver is connected to major blood vessels and the bile duct. The operation is complex and may take several hours. Afterwards, the patient is monitored in intensive care or a high-dependency unit. Breathing support, drains, intravenous lines, pain relief, and frequent blood tests are common during the early period.
The medical team watches closely for bleeding, blood clots, infection, bile-duct complications, poor function of the new liver, kidney problems, and rejection. Rejection occurs when the immune system recognises the donor liver as foreign and attacks it. It does not always cause obvious symptoms, so routine blood tests are essential. Many rejection episodes can be treated when recognised early.
Hospital stay varies according to recovery and complications. NHS Blood and Transplant notes that many recipients can expect approximately one to two weeks in hospital, but some need longer. Recovery continues for months after discharge. Patients should follow their own centre’s instructions rather than comparing their progress with another recipient.
Immunosuppressant medicines
Every liver recipient needs medicines that reduce immune activity and help prevent rejection. These drugs must be taken exactly as prescribed. Missing doses can place the graft at risk, while taking too much can increase infection and toxicity. Patients should never change the dose independently.
Immunosuppressants can cause side effects, including high blood pressure, diabetes, kidney impairment, tremor, high cholesterol, bone loss, and increased susceptibility to infection. Long-term use can also increase the risk of certain cancers, particularly skin cancer and lymphoma. Monitoring allows clinicians to balance rejection prevention against side effects.
Many medicines, supplements, and foods can interact with transplant drugs. Patients should check with the transplant team before taking over-the-counter remedies, herbal products, or new prescriptions. Grapefruit and some related fruits may alter levels of certain immunosuppressants and may need to be avoided, depending on the regimen.
Life after transplantation
Long-term care includes blood tests, clinic appointments, medication review, cancer screening, vaccination planning, and monitoring of the heart, kidneys, bones, and metabolic health. Fever, jaundice, increasing abdominal pain, vomiting, breathlessness, reduced urine, confusion, unusual swelling, or a sudden change in wellbeing should be reported according to the transplant centre’s emergency instructions.
Food safety is important because immunosuppression increases infection risk. Patients may need to avoid raw or undercooked animal products, unpasteurised foods, and unsafe water. Hand hygiene and careful food preparation matter. Vaccination can provide protection, but live vaccines may be unsuitable after transplantation, so all vaccines should be discussed with the specialist team.
Gradual exercise supports strength, cardiovascular health, and recovery. Driving, lifting, work, travel, sexual activity, and pregnancy planning should be discussed during follow-up. Alcohol advice depends on the original disease and transplant policy; some patients must avoid it completely. Tobacco should be avoided because it increases cardiovascular disease and cancer risk.
Emotional and practical realities
Receiving a transplant can bring gratitude and hope, but also anxiety, guilt, fear of rejection, and uncertainty. Family members may experience similar stress. Psychological support and transplant peer groups can help. Financial planning, transport, medicine access, and caregiver support are also important parts of recovery.
A transplant is not simply an operation; it is a lifelong partnership between the recipient and the healthcare team. Successful outcomes depend on careful selection, skilled surgery, reliable medication, close monitoring, and prompt response to warning signs. Many recipients return to active and meaningful lives, but every case remains individual.
